Information

Aims, contents and method of the course

The course will introduce the students into concepts and definitions of environmental colloid chemistry: the role of particle size, the formation of colloids, the different natural colloidal entities as well as the behavior and fate of natural nanoparticles and colloids in the aquatic environment and their analysis in clean and complex environmental samples. Their role in the transport of pollutants and the prerequisites for becoming a relevant pollutant vector will be explained.
General processes as interaction, precipitation, dissolution, aggregation and depostion will be explained and ways of quantification demonstrated. Additionally typical incedental and manufactured nanoparticles will be explained and their similarity with and differences to natural nanoparticles discussed.
Standard analytical techniques for the quantification and characterization of natural and manufactured nanoparticles will be shown and demonstrated in the laboratory. Theses are: Field Flow Fractionation, static and dynamic light scattering and single-particle ICPMS. As far as time and the pandemic allows a few pratical exercises will be conducted.

Assessment and permitted materials

There will be 3 partial examinations:
35% written exam, 45 min. on 11th January 2022; 35% presentation of a scientific paper or report during the January lectures.
30% on exercises to be handed in within one week after the exercise has been handed out. In cases of illness (with doctors certificate) latest until 17.12.2021

The grading scheme is as follows:

> 87% (1); 75-86 % (2); 63-74 % (3); 50-62 % (4); < 50 % (5)35%

Minimum requirements and assessment criteria

Students attending the course successfully are able to describe the fundamental differences of dissolved and particulate compounds in the aquatic environment. They are aware of the different definitions of natural and technical colloids as well as nanoparticles and typical representatives. They can describe processes important for colloids and nanoparticles in the environment as aggregation, deposition, transformation and dissolution. They are familiar with concepts of electrophoretic mobility, zeta-potential, particle size ranges and shape factors and how they influence important processes of colloid stabilization, transport and scavenging. They can recall principles of key instrumental techniques for colloid analysis, namely Field Flow Fractionation, light scattering techniques and single-particle ICP-MS. They know the important representatives of engineered nanoparticles and can apply their knowledge from natural particles to assess their possible reactions in the environment (agglomeration, transformation, dissolution).

The written exam will reflect on course content (lectures & exercises).
The presentation evaluation is done according to
1) preparation of the topic (20%)
2) use of additional sources and information, also coupling to course content (20%)
3) quality of presentation (40%)
4) Q&A part of the presentation (20%)
